Specification of Letters Patent.

Patented May 16, 1911.

Application filed May 28, 1910. Serial No. 563,882.

To all whom it may concern:

Be it-known that I, JOHN RICHARDSON CRAIG, Jr., a subject of the King of Great Britain, residing at Gloucester Mansions. Cambridge Circus, Charing Cross Road,

According to this invention an annulusis employed in place of a disk and this an- 'nulus is loosely held around its edge onto a more or less yielding backing.

Figure is a plan of the record; Fig. 2

is a plan and Fig. 3a section of the holder with the record'in place; Fig. 4c is a plan and Fig. 5 is a section of a modified form of holder.

The holder consists of a disk at of cardboard preferably faced with blotting paper and having a hole a at its center to receive the pin of the gramophone and having upon it a flat ring 6 of cardboad. The outer part b of the width of about half of the circumference of this ring is cemented to the disk as indicated by dotted lines in Fig. 2 but the ring and disk are not otherwise fastened together so that the gramophone record 0 can be passed in and the whole circumference of its edge inserted and loosely held between them.

In the modified form of holder shown in Figs. 4. and 5 the disk a (which as before forms the backing for the record 0 and is preferably faced with blotting paper) is inserted into an'annular frame (l of thin sheet metal provided with a flange a" which prevents the record 0 from escaping.

It is found that an annulus lies much flatter and is less liable to cockle than a disk and that the yielding holding and backing of it greatly diminishes the unpleasant metallic sound common in gramoihones.

The material which it is pre erred to-employ for the record is celluloid and its thickness should be about that of stout paper its flexibility being such that while it is not materially deformed by its own weight it can nevertheless be bent by a very slight pressure.

What I claim is:-

1. A gramophone record, consisting solely of an annulus of thin flexible record-receiving material.

2. The'combination of a thin flexible anrecord consisting of a backing and means for securing one edge of the record to.

holder.

3. The .combination of a thin highly flexible annular gramophone record and a holder therefor, consisting of a yielding sound-absorbing substance and a ring applied to the outer edge of the holder engaging the outer edge of the record.
